摘要: 目的探讨多层螺旋CT 在脑脊液鼻漏诊断中的应用。方法对40 例脑脊液鼻漏患者采用冠状位CT 扫描后重建。结果发现单发颅骨骨质破坏、缺损30 例,显示漏口位置28 例,均与颅骨缺损位置一致;10 例多发缺损可发现两处以上漏口;2 例未直接显示,但副鼻窦腔内有高密度积液,可提示漏口位置。漏口位置:筛窦28 例,额窦后壁9 例,蝶窦上壁3 例。结论多层螺旋CT 是判断脑脊液漏孔位置的有效方法。

Abstract: Objective To investigate the application of multi-slices spiral CT in the diagnosis of cerebrospinal fluid rhinorrhea. Methods 40 cases with cerebrospinal fluid rhinorrhea were examined with multi-slices spiral CT, and their coronal reconstruction images were analyzed. Results Single skull bone defect was found in 30 cases. The leakage positions were showed and consistent with the position of the skull defect in 28 cases. Multiple skull bone defects were found in 10 cases which showed more than 2 leaks. Leakage position was not showed in 2 cases, but the paranasal sinus cavity with high density fluid might suggest leakage location. The leakage positions were located in ethmoid sinus (28 cases), posterior wall of frontal sinus (9 cases), superior wall of sphenoid sinus (3 cases). Conclusion Multi-slices spiral CT is an effective examination to determine location of cerebrospinal fluid leak.
